Distributed Parameter Control of Selective Catalytic Reduction (SCR) for Diesel-Powered Vehicles
DownloadFall 2013
The main scope of this work is to design a distributed parameter control for SCR, which is modelled by using coupled hyperbolic and parabolic partial differential equations (PDEs). This is a boundary control problem where the control objectives are to reduce the amount of NOx emissions and...

Sparsity and Group Sparsity Constrained Inversion for Spectral Decomposition of Seismic Data
DownloadSpring 2012
Local time-frequency analysis, also known as spectral decomposition, allows for a more detailed interpretation of time-series by providing the evolution of the frequency spectrum through time and has proven to be a useful seismic attribute for exercises such as reservoir characterization. This...
